Frank 5c1006dda6 fix(monitoring): scrape node-dankclaw via host.containers.internal
node-exporter is net=host, so its 192.168.0.143:9100 bind is a host bind,
not a published port — the bridge-networked Prometheus container cannot
reach its own host's LAN IP there (netavark DNATs published ports only).
The node-dankclaw target has been red by construction since the
observability cutover while the container reported healthy. Point it at
host.containers.internal:9100 (netavark delivers that to the host LAN IP,
where node-exporter listens) — the same rule frank-large and frank-small
already use. node-dankserver is a different machine and keeps its LAN
address. Update the cross-file contract test and the Targets table.

# LLM fleet. Scraped on the LAN addresses where the endpoint is reachable from

#
# Two metric namespaces, because the fleet runs two runtimes:
#
# * vllm:* — frank-medium (vllm-radiance TP=2 since 2026-09-20): prompt and
# generation token counters, num_requests_waiting plus its reason label,
# num_preemptions_total, the kv_cache_usage_perc fill gauge, the
# prefix_cache hits/queries pair, the spec_decode drafts/accepted triple,
# and real latency histograms (time_to_first_token, inter_token,
# e2e_request_latency).
# * llamacpp:* — frank-large and frank-small. Both take --metrics and both
# were verified 2026-09-20 to export requests_deferred (the queue depth,
# the only form llama.cpp shows the capacity wall in),
# spec_decode_num_drafts_total, tokens_predicted_total, and the
# prompt_tokens_cached_total / prompt_tokens_total reuse pair.
#
# frank-large is scraped over host.containers.internal, not its own LAN address:
# this Prometheus is a bridge-networked container (Network=dankclaw_default),
# and on this netavark host a container can only reach the host's LAN IP at a
# PUBLISHED port — a host-process bind like llama-server's 0.0.0.0:7770 is
# refused at 192.168.0.143:7770 while it answers at 169.254.1.2:7770. That is
# why frank-small was red here for days (up{job="frank-small"} == 0,
# "dial tcp 192.168.0.143:7771") even though the endpoint was healthy and
# exporting: the target address was unreachable by construction, not the
# service down. Same host, same rule, so both local endpoints use the gateway.
# frank-medium stays a LAN address — it is a different machine.
